[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] See also Figure 1-Figure 12 An insulating spacer rod for horizontally isolating conductors provided by an embodiment of the present invention comprises an insulating rod 1, locking units 2 are respectively arranged at both ends of the insulating rod 1, and the structures of the two locking units 2 are consistent. Each locking unit 2 comprises a fixed half ring 2.2 and a movable half ring 2.3. The fixed half ring 2.2 is fixedly connected to the insulating rod 1 through a connecting rod 2.1, and the movable half ring 2.3 is movably arranged on the connecting rod 2.1. The movable half ring 2.3 has: a locking position matched with the fixed half ring 2.2 and a loading and unloading position staggered with the fixed half ring 2.2 in its movable stroke relative to the connecting rod 2.1; a trigger mechanism is also arranged on the insulating rod 1, and the trigger mechanism is used to drive the two movable half rings 2.3 to switch synchronously between the loading and unloading position and the locking position.

[0033] In the above technical scheme, the present invention provides an insulating spacer rod for transverse isolation conductors, in which the fixed half rings 2.2 of the two locking units 2 are respectively sleeved on the two transverse isolation conductors, and then the two movable half rings 2.3 are driven by a trigger mechanism to synchronously switch from the loading and unloading station to the locking station, so that the corresponding movable half ring 2.3 and the fixed half ring 2.2 are used to embrace and lock the conductors, which can provide sufficient gripping force for the conductors, is not easy to loosen during long-term operation, and can withstand the centripetal force of the conductors and fatigue under long-term vibration.

[0034] As a preferred technical solution of the present invention, the trigger mechanism includes two transmission components 4 and an operating component 5. The two transmission components 4 correspond to the two locking units 2 one by one. The two transmission components 4 have the same structure. Each transmission component 4 includes an L-shaped track 4.1, a wedge block 4.2, a slide column 4.3 and a slide rod 4.5. The L-shaped track 4.1 is fixedly arranged on the corresponding connecting rod 2.1. The L-shaped track 4.1 includes a connected horizontal section 4.11 and a vertical section 4.12. The vertical section 4.12 is located at one end of the horizontal section 4.11 close to the corresponding fixed semi-ring 2.2. The wedge block 4.2 and the slide column 4.3 are fixedly connected to the corresponding movable semi-ring 2.3. Specifically, the wedge block 4.2 is fixedly connected to the movable semi-ring 2.3 through a rod body, and the slide column 4.3 is fixedly connected to the movable semi-ring 2.3 through a rod body. 4.3 is fixedly connected to the side of the wedge block 4.2, and the slide column 4.3 is slidably set in the L-shaped track 4.1, that is, the slide column 4.3 can move along the L-shaped track 4.1, and the slide rod 4.5 is slidably connected to the spacer rod through the slip ring 4.4 along the length direction of the spacer rod. Specifically, the slip ring 4.4 is slidably connected to the insulating rod 1 along the length direction of the insulating rod 1. The slip ring 4.4 is fixedly connected to the corresponding slide rod 4.5 and is hinged to the corresponding connecting rod 5.3; the slide rod 4.5 is slidably connected to the inclined surface of the wedge block 4.2. Specifically, the two are not just abutted, but have a sliding structure, such as the cooperation of a slider and a slide groove, and the slider must not be separated from the slide groove; the operating component 5 is used to drive the slide rods 4.5 of the two transmission components 4 to slide synchronously in the opposite direction relative to the insulating rod 1.

[0035] In this technical solution, after the two wires are respectively enclosed by the two fixed half rings 2.2, the operating component 5 drives the slide bars 4.5 of the two transmission components 4 to slide synchronously in the opposite direction relative to the insulating rod 1. For any transmission component 4 and its corresponding locking unit 2, refer to Figure 1-Figure 3 , Figure 7-Figure 8 The slide bar 4.5 applies abutting force to the wedge block 4.2. Due to the restriction of the horizontal section 4.11 on the slide column 4.3 in the vertical direction, the slide bar 4.5 does not slide relative to the wedge block 4.2, but the slide bar 4.5 pushes the wedge block 4.2 to move horizontally, and the wedge block 4.2 drives the slide column 4.3 and the movable semi-ring 2.3 to move together. The slide column 4.3 slides along the horizontal section 4.11 until the slide column 4.3 slides to the junction of the horizontal section 4.11 and the vertical section 4.12. At this time, the movable semi-ring 2.3 is just in contact with the fixed semi-ring 2.2 completely overlap in the vertical direction. As the slide bar 4.5 continues to slide, due to the restriction of the vertical section 4.12 on the slide column 4.3 in the horizontal direction, the wedge block 4.2 cannot continue to move horizontally. The slide bar 4.5 and the inclined surface of the wedge block 4.2 slide relative to each other, so that the wedge block 4.2 slides vertically through the cooperation of the slide column 4.3 and the vertical section 4.12, thereby driving the movable half ring 2.3 to fit on the fixed half ring 2.2. The movable half ring 2.3 and the fixed half ring 2.2 embrace and lock the corresponding wires. See Figure 4-Figure 6 , Figure 9-10. Thus, the two locking units 2 can lock the corresponding wires synchronously.

[0036] As a further preferred technical solution of the present invention, the operating component 5 includes a vertical rod 5.1, a connecting piece 5.2 and two connecting rods 5.3. The connecting piece 5.2 is rotatably connected to the vertical rod 5.1. One end of the two connecting rods 5.3 is hinged on the connecting piece 5.2, and the other end is respectively hinged to a sliding rod 4.5 of a transmission component 4. The vertical rod 5.1 is movably arranged on the insulating rod 1. The vertical rod 5.1 has a threaded section 5.11. The insulating rod 1 is fixedly connected with a nut 5.5 through a hollow rod 5.4. The vertical rod 5.1 passes through the hollow rod 5.4 and the nut 5.5. The vertical rod 5.1 has a movable stroke relative to the insulating rod 1: a first stroke in which the vertical rod 5.1 slides vertically relative to the insulating rod 1, and a second stroke in which the vertical rod 5.1 is threadedly matched with the nut 5.5 through the threaded section 5.11.

[0037] In the present technical scheme, in the first stroke, the vertical rod 5.1 slides vertically relative to the insulating rod 1, thereby driving the connecting piece 5.2 to move together, and the connecting piece 5.2 drives the two sliding rods to slide synchronously in the opposite direction through the two connecting rods 5.3; in the second stroke, the vertical rod 5.1 rotates relative to the connecting piece 5.2, and the threaded section 5.11 on the vertical rod 5.1 is threadedly connected with the nut 5.5 on the insulating rod 1, thereby achieving relative locking between the vertical rod 5.1 and the insulating rod 1, and also realizing the locking between the movable half ring 2.3 and the fixed half ring 2.2 of the two locking units 2 after embracing the conductor.

[0038] In one of the embodiments provided by the present invention, refer to Figure 1-Figure 2 , Figure 4-Figure 5 The end of the vertical rod 5.1 is fixedly connected with an operating ring 5.6. It needs to be used in conjunction with the insulating operating rod to install the insulating spacer rod for the horizontal isolation wire on the ground. The specific operation method is to insert the top of the insulating operating rod horizontally into the operating ring 5.6. Fig.11, the operating ring 5.6 is lifted upward by the insulating operating rod, so that the vertical rod 5.1 drives the connecting piece 5.2 to move upward relative to the insulating rod 1, so that the movable semi-ring 2.3 is placed in the loading and unloading position through the connecting rod 5.3 and the transmission assembly 4, and the opening of the fixed semi-ring 2.2 faces downward. The insulating operating rod is used to lift the insulating rod 1 from between the two wires to above the wires in a manner parallel to the transverse isolation wire. Then the insulating operating rod is rotated 90 degrees so that the two fixed semi-rings 2.2 are located directly above the two wires, and the insulating operating rod is lowered so that the two fixed semi-rings 2.2 are respectively hung on the corresponding wires. The insulating operating rod is further lowered so that the vertical rod 5.1 drives the connecting piece 5.2 to move downward, that is, the vertical rod 5.1 is lowered for the first stroke, and the movable semi-ring 2.3 is driven by the connecting rod 5.3 and the transmission assembly 4 from the loading and unloading position. The workstation moves toward the locking workstation until the movable half ring 2.3 is about to reach the locking workstation, and the threaded section 5.11 of the vertical rod 5.1 abuts against the nut 5.5, exerting a downward pulling force on the insulating operating rod and rotating the insulating operating rod, so that the vertical rod 5.1 rotates relative to the insulating rod 1 through the operating ring 5.6, and the threaded section 5.11 and the nut 5.5 begin to be threadedly connected and cooperated, so that the vertical rod 5.1 continues to move downward slightly relative to the insulating rod 1, causing the movable half ring 2.3 to continue to approach the fixed half ring 2.2 to hold the wire tightly, and after the insulating operating rod is removed, the vertical rod 5.1 is locked relative to the insulating rod 1 through the threaded section 5.11 and the nut 5.5, and the movable half ring 2.3 is also locked in the locking workstation, and the movable half ring 2.3 and the fixed half ring 2.2 firmly hold and lock the wire.

[0039] In another embodiment provided by the present invention, the participants Figure 7-10A spiral rod 5.7 is fixedly connected to the vertical rod 5.1, and a spiral groove is opened on the peripheral side of the spiral rod 5.7. A movable sleeve 5.8 is sleeved on the spiral rod 5.7. A ball is rolled and embedded on the inner wall of the movable sleeve 5.8. The ball rolls along the spiral groove. An operating ring 5.6 is fixedly connected to the movable sleeve 5.8 through an extension rod 5.10. A magnetic attraction structure or a clamping structure is provided between the operating ring 5.6 and the end of the spiral rod 5.7. Since some existing insulating operating rods are not convenient for rotation operation and are only used for lifting or pulling down, in this embodiment, after the two fixed half rings 2.2 are sleeved on the corresponding wires, by pulling down the insulating operating rod, the operating ring 5.6 drives the spiral rod 5.7 and the vertical rod 5.1 to move downward through the magnetic attraction structure, so that the threaded section 5.11 and the nut 5.5 are docked, and then there is no need to rotate the insulating operating rod, but continue to pull down the insulating operating rod. Since the threaded section 5.11 of the vertical rod 5.1 is blocked by the nut 5.5 and cannot continue to slide down relative to the insulating rod 1, the operating ring 5.6 overcomes the force of the magnetic attraction structure and breaks away from the spiral rod 5.7. The operating ring 5.6 drives the movable sleeve 5.8 to descend through the extension rod 5.10. The movable sleeve 5.8 rotates the spiral rod 5.7 and the vertical rod 5.1 through the cooperation between the ball and the spiral groove, so that the threaded section 5.11 and the nut 5.5 are tightened, so that the movable half ring 2.3 is locked in the locking position to cooperate with the fixed half ring 2.2 to lock the wire.

[0040] This embodiment also has another effect, see Fig.12, that is, it can be installed on the horizontal isolation wire with the help of a drone. Compared with the installation method through the insulating operating rod, the insulating spacer installed by the drone is inverted on the horizontal isolation wire. The specific operation method is to connect the operating ring 5.6 to the drone through a pull rope, and then the drone lifts the insulating spacer through the pull rope. The magnetic suction structure makes the operating ring 5.6 and the spiral rod 5.7 adsorbed together. There is damping between the active matching structures of the transmission component 4, such as rotation damping between the connecting piece 5.2 and the connecting rod 5.3, or sliding damping between the sliding rod 4.5 and the insulating rod 1. The purpose is to keep the active half ring 2.3 at the loading and unloading position. The drone lifts the insulating spacer to the top of the horizontal insulated wire, so that the insulating rod 1 of the insulating spacer drops from the bottom of the wire between the two wires in a manner parallel to the wire, and then the drone drives the insulating spacer to The insulating spacer is rotated 90 degrees, and the drone is pulled up again, so that the two fixed half rings 2.2 are respectively set on the corresponding wires, and the drone continues to pull up, and the operating ring 5.6 overcomes the force of the magnetic attraction structure and separates from the spiral rod 5.7. The operating ring 5.6 drives the movable sleeve 5.8 to move up relative to the spiral rod 5.7 through the extension rod 5.10. The movable sleeve 5.8 rotates the spiral rod 5.7 and the vertical rod 5.1 through the cooperation between the ball and the spiral groove, so that the threaded section 5.11 and the nut 5.5 are tightened, so that the movable half ring 2.3 is locked in the locking position to cooperate with the fixed half ring 2.2 to lock the wire, and then the drone can cut the pull rope, or the pull rope is hooked to the operating ring 5.6 through the hook, and the drone slightly descends to relax the pull rope, and the hook can be separated from the operating ring 5.6 due to its own weight, so as to achieve the separation between the drone and the insulating spacer.

[0041] As a preferred technical solution of the present invention, a first insulator 3 is provided on the insulating rod 1, and the first insulator 3 is located between the middle of the insulating rod 1 and one of the locking units 2, and a second insulator 5.9 is provided on the connecting rod 5.3 corresponding to the locking unit 2. The first insulator 3 and the second insulator 5.9 can increase the insulation effect between the two locking units 2, especially in rainy and snowy weather.

[0042] As a preferred technical solution, the fixed half rings 2.2 of the two locking units 2 are respectively fixedly connected with inclined guide rods 6. When the spacing between the two transverse isolation wires is greater than the spacing between the two fixed half rings 2.2, the guide rods 6 can guide the two wires into the corresponding fixed half rings 2.2. In addition, the movable half ring 2.3 has another function. When the movable half ring 2.3 is in the loading and unloading station state, when the spacing between the two transverse isolation wires is less than the spacing between the two fixed half rings 2.2, the outer arc surface of the movable half ring 2.3 can guide the two wires into the corresponding fixed half ring 2.2.

[0043] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
